Everything went well, the communication with Marisa was good, and the instructions regarding the check-in were clear. The room is like in the pictures and although I was afraid it would be noisy at it is faced to the street, it was actually one of the quiet places I stayed in. The bed was also good, and I slept really well and I am a sensitive person, so it says a lot.
The apartment is close to the metro station on green line, which basically takes you anywhere you need, but also close the the red line which has direct route to the airport, so it was the perfect choice for me. Around the building are a few restaurants, shops and everything you might need, so no need to worry about not finding something. :)
The only downside I will say is the door of the room, which doesn't close so easy, but I was expecting it as it was also mentioned in other reviews. It's not impossible to close it, you can manage it and I think it's a big plus that you receive a key of the room anyway.
