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.

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.

All you need for a comfortable stay

We like the flexibility of an apartment rather than a hotel, but were pleased to find the same level of facilities as a good hotel. Great to have full sized toiletries, a well equipped kitchen, working WiFi and good air conditioning. This apartment was close to everything we needed,, transport links, restaurants and shops. We did ask for a late check out which was dealt with very efficiently. We will use Sonder again if they are in the right location.
