Probably, my best stay in several years.
Location is great — historical center and historical building itself (however, there is an elevator, which is very rare in such houses);
Flat is very, very cool: stylish, lots of wood, well-lit rooms, nice water pressure and temperature;
WiFi is very fast and reliable, I haven't try gaming, but I have no problems working and having videocalls;
Ali met us in the middle of the night due to delayed flight, we really appreciate it;
Extremely easy checkout;
There are many little things to make your stay as easy as it could be: coffee machine, tea, sugar, some sweets, bottle openers, candles. There is even a clothes waching service — we gave our clothes and got them back clean, tidy and dry!
Overall I have only positive emotions about it and highly recommend to all to stay there :)
