We loved our stay here, the location was great (walking distance to all the iconic sites) and the view was absolutely incredible and worth the stairs! The elevator is not on the ground floor so there are stairs leading up to that and then additional steps leading to the rooftop inside the apartment - but again, we found it totally worth it. Our check in and check out went very smoothly (we were even allowed to check in a little bit early), and there was wine for us on our arrival which was such a treat! Communication was easy and our host was so nice and also generous with his time and explanations during check-in.
Just a couple things that might be helpful to know if you're planning on staying - make sure you bring your own toiletries (there is hand soap but no bath/shower toiletries) and the paper towels were at the end of their roll when we arrived so you may need to buy some. The wifi was strong in the main living room and lofted bedroom above it but not great in the main bedroom (and not present on the roof, which is understandable). The noise at night is something to consider - there is a rowdy bar across the street where people were out until at least 3am during weeknights, and there were all-night parties in the apartments below us in the building with very loud music each night we were there - If you can't sleep with lots of noise make sure you bring some earplugs!
Overall, we would definitely recommend this place to others and would absolutely stay again. It was perfect for accessing all the areas we wanted to see and the rooftop was really something special, we spent all of our non-sight-seeing time up there with coffee or wine, and we really enjoyed our stay. Thanks again to our great hosts!
