ACID Café

This is the best tasting espresso I’ve had since I’ve been in Europe traveling! They are an excellent specialty coffee shop. I also tried the cinnamon roll and enjoyed it but it was a little too crumbly and fell apart on me. I guess I’m used to more doughy type of cinnamon rolls but it was still delicious. The staff were excellent and extremely warm and friendly. The place inside doesn’t have any air conditioning so it’s a little warm on a really hot day but they do have fans to help move the air around. I’d highly recommend this spot and I hope I can come back before I leave.

Acid Café in Madrid was exactly the reset we needed after a long travel day. We ordered two flat whites and a cardamom bun—and honestly, wow. The coffee? Absolutely dialed in. While you won’t find dramatic latte art here, the flavor of their single origin espresso speaks for itself—smooth, rich, and perfectly balanced. It’s the kind of cup that makes you stop mid-sip just to appreciate it. It’s a Nordic coffee, which makes it super unique. The cardamom bun was a knockout—warm, just the right amount of spice, soft with that slightly chewy pull you hope for. Paired with the flat white, it was the perfect way to shake off the jet lag fog. Vibe-wise, it’s got this cool, under-the-radar energy. Great music humming in the background, super talented barista working the machine like an artist, and genuinely kind service. Definitely a spot I’d come back to again and again.

We saw positive reviews for the coffee online and decided to try it. It wasn't particularly special, but it seemed like a typical flavor to us. But the muffin was truly delicious, and I'd say it was worth the trip.

Had coffee and croissants. For some reason they don’t have Americano. They do have espresso and the regular coffee is filter/batch?. There is no WiFi and the data connectivity once you are in is pathetic. Drops to 3G and nothing works. So if you are seeking a coffee in “peace” come here. I wouldn’t go back- only because of the data issues.

Everything super nice but 8€ for 3 spoons of yogurt with granola, I think it’s too much. We were waiting for a bowl but it came a bowl which the quantity was so small.

Very good experience! ദ്ദി(˵ •̀ ᴗ - ˵ ) ✧ I ordered an iced latte with oat milk and a cinnamon roll. The iced latte was perfectly balanced and the oat milk was of good quality, as for the cinnamon it was very feuilleté which -as a French person- I loved, and the topping was kind of sour but it actually balanced with the sweetness of the pastry itself. I'll go back when I visit Madrid again ⭑.ᐟ

The cafe has a minimalist and simple decor. Their coffee is of very good quality. The staff were very kind, if we pass by again we will definitely go there for a coffee again.

I come here since they opened. Great bakery and pastries, concious and accessible facilities, but I would like to make a complaint as I noticed the kind baristas working hard with no air conditioning or enough fans in these increasing temperatures in Madrid (this week up to 37*) Management take care of your workers!!!

Love this café! Came by here a few times a week for their rotating menu of pour over coffee, all of which were great. Their pastries are also great, with the cardamom roll and Berliner both standouts. Definitely a great place for a quick coffee and people watching, although Acid is marginally pricier than other coffeeshops in the neighborhood.

Great selection of coffee, fresh pastries, good music and fun staff. Highly recommend.

Coffee bliss! The coffee here is legit! The chai, divine. We also had an amazing green tea. The homemade baked goods are divine. This is no ordinary spot! Take time to slow down, bring a book and savor some coffee! We loved Acid!!

Amazing food great service highly recommended there salmon sandwich was so good. Coffee is fresh.

Nice coffee spot at a short walk from the Parque del Retiro. I had a good and refreshing Espress Tonic which is not that common in other places around Madrid.

This is a new spot as I understand. The esthetics are just wow. Had a Cortado, not the best I had in Madrid but very smooth which is refreshing and different from the strong espresso I've come to appreciate. I have however had the perfect Rogaliki (a Ukrainian sweet) that is just the right amount of sweet. The owner is a young Argentinian fella that is just down to earth and super kind. Love it when I get to meet the people behind these lovely coffee houses.

Visiting from Miami, Florida, there is a coffee shop on every corner. If you're in Madrid though and you want great coffee -I've never had coffee like this before- in a very comfortable environment where the owner greets you and allows you to make his shop your home, even if for a brief moment, then Acid is a must visit. The food is excellent as well.... I had a latte along with a granola bowl of berries and kefir.... and nothing disappointed! In our 5 days here, this is our 3rd visit here. I hope when you visit you enjoy it's much as we do!
