I had a 2-night stay at Maria's place.
Pros: It is very centrally located, just steps away from everything. The place was clean, spacious and well equipped.
Cons: I personally found the check-in time to be a bit inconvenient (4pm, which is later than most other accommodations) especially without the possibility of leaving our luggage there. The building does have an elevator however there is a long flight of stairs to reach it as it begins on the next floor. We also found the room to be quite noisy as you can hear people walking above and on the stairs. Due to the position of the windows, it was quite dark with no natural lighting.
