My friend and I stayed for 4 nights in this place. It was very close to the center, we never used the metro as everything was a reasonable walking distance from the apartment.
The place itself lacks some natural lighting, and it can be a little noisy sometimes because the windows give to a small patio where the neighbors live too.
Check in and check out were done efficiently with several friends of the host (they didn’t speak perfect english but enough to understand each other).
We would recommend staying here as the quality/price ratio is quite amazing :)
