We really had a great time in Prague. It was very easy to find and check in to the flat. Both, check in and check out were very easy thanks to Adam's great information.
We loved the old building the flat is located in. Especially the wooden floor. Unfortunately, old houses like this are not isolated pretty well and our flat neighbour was watching tv constantly all day. He/she started watching tv series at 5 o clock in the morning and we could hear every word of Big Bang Theory or King of Queens. So don't forget your earplugs. Gladly we were only there to sleep and left early and came back late.
Bathroom and toilet are shared with three other rooms. It was as clean as it can be for this amount of people.
All in all it we had a great time in Prague. We nearly walked everywhere and only took public transportation twice. Flat is located perfectly with a lot of nice cafes and restaurants close by. We can totally recommend staying at Adam's, especially if you want to travel on a budget and want a nice and clean room.
