My husband and I do quite a bit of first class travel (I say this to give you a context in which to evaluate my review). Dan has done a very good job of dressing up his space in a 200-year old building, thus there are some charming touches not only architecturally but also in the style and decoration of the flat. Everything worked perfectly and we felt comfortable and safe. Although we spent very little time in the flat we appreciated the high quality linens, excellent TV access and sound system. We did not use the tiny kitchen area but there is access to coffee, microwave, small fridge and what I believe was a toaster oven. As might be expected the bathroom is very small with a tiny shower. Even so, the shower worked perfectly so we were quite satisfied.
Guests should be aware of the following: 1) there are ways in which the building shows it age. 2) At the time of our visit there was construction across the street with pounding & drilling, surprisingly late into the night. 3) As others have mentioned it is right on the street so expect noise. Despite this we slept well because the air conditioner provided a partial cover with its "white noise" and the bed was comfortable. 4) Although I loved the large windows and light, they looked out onto the construction site and three large garbage cans on the sidewalk below that were overloaded at the time we arrived, never emptied and were surrounded by piles of garbage bags when we left 4 days later. Naturally none of this is under Dan's control.
The neighborhood is lively with many good restaurant choices. Despite Dan's being in a great deal of pain and difficulty from a very serious recent accident, he was very prompt in communication and very helpful with suggestions about transportation, restaurants, and places to visit in the city.
