We stayed in this flat for a month. The neighborhood was absolutely perfect for us - quiet but very easily walk-able to anything we needed (including the metro and public markets). The apartment itself is beautiful and extraordinary in terms of space/size.
For us, the apartment wasn't set up super well for a long-term stay (e.g., one dish towel, no extra sheets, not much in the way of cleaning supplies). We also found some issues with cleanliness and repairs (e.g., dust, broken drawers). The team at Get-a-Key was very willing to work with us, but between a couple delays in their responses and some constraints on our side (a few people in our group caught colds), we weren't able to get the issues resolved during our stay. All issues are easily solvable and based on other reviews not chronic for this apartment - we would stay here again.
