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.

This is a fabulous property. If you're staying in Madrid the location couldn't be better. The check in and out is super easy, and the apartment was a great size for our family of four. The personal touches left by the Sonder team were gorgeous. We mentioned that it was our daughters birthday and when we returned that evening she found a note and some lollies to help celebrate her day. We couldn't have asked for more from our stay and we will definitely be rebooking. Thanks Sonder, you really made our stay memorable.

Heart of Central Madrid, super convenient, very close to Puerta del Sol. Spacious 1 BR w/ pullout sofa bed. Comfortably sleeps 4 people. Washer in unit and bathroom is clean. Only negative is that it gets very loud at night as there are night clubs adjacent and across the street. Hotel Sonder team who comes to bring you supplies is so sweet and nice! Be aware though this location will charge you if you ask for more than 1 replacement if towels. Otherwise, it's spacious, centrally located, and will make your stay in Madrid east and enjoyable.

Great except for a glitch

Everything was great until we couldn't get back into our room to get our bags an hour before check out. We hadn't checked out yet the code didn't work anymore. Thankfully a cleaning staff happened by and opened the door.

Place was conveniently located with everything I needed. However, it was very loud with no soundproofing. I could hear people talking/ walking/ using the bathroom in other units like they were next to me. The noise from the club and street below could almost be drowned out if the fan was on max.

Great location

Great stay. I would recommend Sonder as al alternative to hotels, especially when travel with family. The location of this Sonder is perfect and close to all of Madrid famous landmarks at the city center. Close to public transportation and right above a mini market which made eating or having some snacks at the property very convenient.

Caution - photos do not show real state of room

I recently stayed at Sonder Santa Ana in Madrid, and it was one of the most disappointing experiences I’ve ever had. The photos on their website (which influenced my decision to book) show a new, modern, clean, property, but the reality could not have been more different. The room was outdated, poorly maintained and dirty. Upon arrival, I discovered hairs in the bathroom, and when I requested housekeeping to address the issue, the response was apathetic. Adding to the frustration, I attempted to cancel my entire three-night stay due to their blatant misrepresentation of the property, but the staff refused to refund the first night and only agreed to cancel the remaining two nights. I was left with no choice but to endure one night due to their inflexibility. To make matters worse, at night, people congregated and smoked outside the main entrance, filling the property with the smell of cigarettes that made its way into my room. The most egregious issue, however, is the blatant misrepresentation of the property. The images on their website bear no resemblance to the actual state of the rooms (see attached photos). This is not just unethical—it is outright deceptive. I strongly urge anyone considering staying at this property—or with Sonder in general—to think twice. My experience reveals a company that utilises doctored images, slick apps, and flashy marketing to mis-sell. Customers deserve not to be deceived. This was my first and last Sonder experience!

Very Loud

Good location and size but very loud. Club under the hotel goes to 4:30 AM and sound insulation was poor overall. Always a bad sign when they have free earplugs next to your bed.
