We had a great time at Anna's place. The flat is beautiful and was equipped with everything we needed for a 3-nights stay. We especially loved that the charm of the old building had been kept, with the arched ceiling and the tiled stove. The flat is located on a central street with nice houses, only a five minute walk from Charles bridge and Prague castle. We could walk everywhere and only used public transport to get there from Florenc station upon arrival (which took us about 20 min). Anna was very welcoming and gave us some helpful tips for going out. We would definitely choose to stay here again.
I'd still like to point out two things: The bathroom could use a shower curtain (we somehow flooded the room every time we took a shower.) Also, there was construction work going on on the ground floor of the building, which didn't cause any disturbance most of the time but woke us up quite early in the morning.
