Maria’s apartment is quite convenient, for its location. Easy walking distance to the grocery and main sites. I stayed here for a month and it was good overall. It is small but has everything you need. She was helpful and got us extra sheets when my parents visited.
However, as others have noted, there is some noise from the street at night, which can be loud during the weekends. There is also a really loud buzzer next door to the bedroom which is annoying. The apartment is in the ground floor and it sees no sunlight at all, so it was cold some times. I told this to Maria and she kindly brought in an extra blanket and let us use the heater for some hours a day. All these issues won’t be a big deal for a few days maybe but wanted to share in case you are staying longer.
