Hello, I never complaint. But, by far this was the worst room I’ve ever stayed in. The AC units? Purely decorative, except for the noise, which works exceptionally well. The wall filtration adds a nice visual touch, marks on the walls all over, including a couple of buggers, dead plants in the terrace. And to top it all off: no hot water for a morning shower. What more could one ask for?

Property was lovely once we finally got in. But after a month of emails from them requesting our phone number while in Spain and us responding that we will only have data and could they please use email to give us the code. The result was us waiting at the front door for an hour and a half.

Maybe try the other Sonder Madrid location

Pros: 1) central location - quick and easy to get anywhere in the city. 2) communication was fast and supportive. They also have someone on-site to help if needed (which isn’t always the case at aparthotels. 3) beds were very comfortable. 4) the water dispenser was very convenient. Cons: 1) super loud club is close by and the bass thumping could be heard throughout the night, until about 5-6am. To their credit, Sonder provides earplugs… but not an ideal sleeping situation. 2) the rooms are very dark with the living space having no natural light. Overall, I’d give Sonder another chance, but I can’t recommend this location due to the loud music alone and our lack of sleep because of it.

Great location. Very clean and comfortable with nice air conditioning. The beds were so comfortable. The apt. was 2 stories and allowed us some privacy and separation. Very nice bathrooms. This was a great place to stay and highly recommend it.

We booked this hotel at the last minute due to travel plans changing due to the power outage. It is a bit strange that you have to upload all your details but actually worked out fine as we were able to enter the property without any person checking us in. It is in the centre of the city and it is an old building so a bit noisy at times but safe.
