Marty is a very nice host, he met us at the arranged time and welcomed warmly. Marty's place is very spacious, clean, stylish and comfortable. It has got everything you need for a pleasant stay. I personally really liked the 2 terasses where it was very nice to enjoy the coffee and perfect weather. Also it's very important that we had separate really nice bathroom/toilet. The location is quite good - only 5 min to tram station. The building itself and the yard are very modern and cute.
In general, it is a very good option for a vacation in Prague for two. Many thanks to the hosts - Marty and Tomas!
