We stayed for 12 days at Martas apartement and had a good time. Everything we needed was there (fully equiped kitchen, towels and even a hairdryer). Thanks to two electrical heatings, we were able to heat the flat.
Two things to mention anyway: the street wasn't as calm as we expected it (but earplugs will do a good job here) and due to a small high temperature boiler the hot water was just enough for one person to shower (but that's nothing that couldn't be managed).
The arrival and leaving were easy to organise with Marta, as she reponses within a day to all messages. Also she placed some starters (fruits, water, coffee and so on) in the flat for making the arrival a lot easier. Thank you for the nice stay, Marta!
