I would stay here again for sure. The location was second to none, with groceries, cafes, shopping, and historical sights close by. The Metro is five minutes walk and you can get everywhere. Alberto is a gem. He was always reaching out to make sure we were doing OK, and giving us tips and suggestions. Upon arrival we found all sorts of treats to make us feel welcome. Truly lovely.
A couple things to note: the beds and linens are super comfy, the bathroom is very tiny but manageable. The only real window is in the master bedroom and it faces the street, so if you are light sleeper then maybe pack some ear plugs. There is natural light in the flat but windows look out on walls so it can feel a little claustrophobic. However, with all the things to do and see during the day you only end up falling into bed at night anyway. Everything you need to make light meals is in the kitchen — so that was fantastic.
All together a wonderful, clean and centrally located place to fall into bed at night.
