We (party of 3) spent five nights in August 2022 at Dina's place. Overall our experience was that:
On the positive side, communications with Dina was easy and timely, and she was very responsive. The instructions to get to the apartment and to get the keys were also clear. The apartment was exactly as in the picture, it was clean and well organized. The accessories (TV, small fridge, etc) were basic but working well. As other guests already said, the apartment is in a great location in central London, near theaters, restaurants and tourism attractions.
At the same time, there are a few items future guest should consider: (1) the steps are indeed steep and depending on the floor you stay, it can be hard going up the stairs (late in the day or with heavy luggage). (2) the bathroom is really very small, with limited space to move, specially in the shower. (3) due to the great location of the apartment, it gets noisy during the afternoon and night as the restaurants and pubs are open until late and people are not shy to scream and talk loudly in front of the apartment.
In our case we manage these issues and had a nice time at Dina's place.
