The apartment is fine, spacious and the location is good.
We did not meet some one personally at the check in or check out. The contact was accurate per sms though and they answered instantly.
Unfortunately there had been an incident with the car. We had chosen to stay in Vaclavs apartment because in the advertisement was said it had a free parking option (by now the owner changed the tekst). During our stay we had to move our car incidently because of works at the yard. Fortunately we were at home on that moment and could take the car away. Vaclav referred us by tekst messages to a specific parking place in the neighborhood assuring us that the car would be safe there. Next they we found the car with a wheel lock though and it took us time and money (1000 krone) to get it removed. Unfortunately Vaclav did not take responsibility for the fact that he had referred us to that place neither did he answer anymore to our messages.
There had also been a problem with the water. We had hot water during the first two days of our stay then it was icy cold. When we asked Vaclav if it could be solved he teksted us how to reset the boiler but we could not solve it and only had cold water to shower.
All in all we had a very nice time in Prague. If you don't count on parking the car and if the water issue is solved, the house in itself is very fine, the beds are good and the location perfect.
