Sofia's place is located in an area, which is very close to the city centre (we barely used any public transport), while you can still find nice local bars in the neighbourhood, which are not filled with tourists.
The apartment itself is spacious and very fitting for 1-3 people. The kitchen has everything you need, same in the bathroom, living room and bedroom. While we enjoyed the apartment, the hospitality, the communication with Minty (an organisation that helps Sofia with communicating with the guests), there is a one very big minus - thin walls.
I have noticed that there are other reviews about the noise level and these people are not exaggerating as you can here every person that is walking in the corridor and passing the front door. This is especially problematic in the mornings, when people go to work or drop their kids (who obviously run in the corridors) to school. We would be constantly woken up by literally every person that is in the corridor and while people in the upper floors probably use the elevator, as the apartment is on the 2nd floor, there are still plenty of people who use the stairs.
So for the future guests - if you are there for work or you plan to wake up around 6-7AM anyway, then this is a very nice place to stay. However, if you are there for a holiday and would appreciate sleeping in or even until 9-10AM, then I would suggest you to find another place. It's really a shame about the noise, as everything else is really great.
