Sebastian is a lovely guy and a pleasure to deal with. The flat is well located within walking distance of the city or the No 49 tram (which you can see opposite the square) will take you there in a few minutes. Also opposite is the metro which is deservedly one of the best in Europe. We got a 17E weekly pass for all transportation and it's so easy to use with no turnstiles or validation required. The flat is very spacious, which is good as it looks like Sebastian lives here part of the time and so it's quite cluttered and the bedroom feels a bit claustrophobic. Some details need to be improved but all-in-all a good experience, if not a great one.
