Marta's place is 5 min walk from the train/bus station so very convenient. It's on a busy street though so you can hear cars all night.
Marta was a nice host - she let us check in earlier so we could leave our luggage at her place before exploring the city, which was very nice. She also recommended us what to see and where to go.
Our room was spacious and clean (as well as bathroom), although it smelled a bit like people were smoking there. Maybe it was not the case but this was our impression. For one night it was fine though, and since we had to catch an early morning flight back home, we really liked the location just 5 min from the bus station to the airport.
