We strongly recommend staying at Martin's apartment. Everything was perfect. We have nothing to complain about. The bed was really comfortable. The bathroom was great too. Martin also allowed us to use the kitchen so we could keep cold drinks in the fridge. Everything was super clean. We felt extremely safe in the flat and neighbourhood which was peaceful. Although the flat is not in the city centre, you can get there within 10 mins by metro which is in walking distance from the flat. it's also very close to the airport. It took us about 10 mins to get there by bus. Both the check-in and check-out went really smooth. Martin is a great host and seems to be a really friendly guy. 10/10 :)
