It was a great stay in Christian's place. The mail from Christian tells everything, directions, transportations, how to use washing machine, etc. The flat is modern, well-maintained, and located in a local area where you can reach city center by bus or metro in 10 minutes. It takes about 15 minutes walk if you first come to the flat by tram or metro, BUT you can take the bus 48A to reach to metro or tram when you are leaving, so it saves you 10 minutes. (The road is one-way)
The kitchen equipped everything that you'll need, and the badroom is lovely. Sleeping quality is quite good since this is a residental area. There is a shopping mall near the flat, it takes 5 mins to walk there, an it includes supermarket, H&M, candy shops, etc. Highly recommend Christian's flat! You won't regret!
