We were in appartment 1 and it was lovely. It is greatly situated in the city center and everything you need is close around. Actually, the street in front of the appartment is busy and noisy, but with windows closed at night we weren't bothered at all. Communication with the host was easy and he answered alwasy very quickly. The only thing we had troubles with was the shower - there wasn't enough hot water for both of us to shower, as it needs to be heated up in the boiler which takes some time. So better be quick and plan your showers or it gets cold ;)
