We had a lovely stay in Maria's apartment. Maria was nice enough to allow us to check in late for a small fee and we were welcomed by someone who showed us around in the late evening.
The courtyard of the residence is beautiful and you feel like you're in a fairytale. The apartment itself was very clean and you had everything you needed really. It was in a great location too - easy to walk to a lot of different sites. We never took a cab anywhere!
The apartment is relatively quiet - however, it is not entirely silent when you're sleeping. The staircase of the residence (which has a gate) is on the other side of the wall in the bedroom so you can hear the other residents enter and leave in the morning and during the night. However, as a light sleeper myself, this didn't bother me too much as the other residents were quiet otherwise and didn't make any extra noise.
The only negative from the trip was the very front door of the entire residence. This was difficult to open and required heavy shoving. On our last night, we were nearly stuck outside in the middle of the night if another resident hadn't decided to help us get in! When we were getting in for the last time the next day, my friend injured her hand trying to open it. We hope it's been fixed now so other travellers don't have issues. However, overall, we had a great stay here despite the door situation!
