This is a beautiful apartment with a lovely view. It's complete with all the necessary amenities, the common area gets a lot of sunlight, and it's a very cozy environment to work from home. The hosts are also incredibly friendly and helpful.
There are many supermarkets at walking distance, fun places to enjoy nightlife, and it is right in front of a convenient metro station that is just a few minutes away from Retiro park. If you stay in Madrid, I highly recommend staying here!
