We enjoyed our stay at Olga's apartment very much. The location is very close to the main attraction and Imogen parking garage. And during the night there is no noise from the main street that can be heard. The building is beautiful, although in the evening we felt like we had to speak in soft voices because of the echo and absence of sound isolation.
I am also a very light sleeper so the movements, foot steps, as well as the occasional barking of the dog from the apartment above made it a little bit harder for me to sleep. But my husband was totally fine with the minor nouses.
Apartment in itself is very cozy and has everything you would need. The hosts were very reachable and friendly. We would recommend this place!
