My mother and I spent four nights in Ulvi's flat and had a good time. The flat is about 20 minutes walk from the old town, so it is very central due to Pragues size. Both the Florenc bus station and the main train station are a 10-minute walk away. There is also a supermarket and a tram station just around the corner.
The staircase is not very inviting, but Ulvi points this out beforehand and it is not his fault, as he is only responsible for the flats.
The flat itself is small and designed for a maximum of 2 people. There is also only one duvet, so I would mainly recommend couples to stay here. Unfortunately, you can only open the bathroom window in the flat, so it is difficult to ventilate. Also, the kitchen is not very well equipped, e.g. there was neither a can opener nor scissors. There were no extra bin liners and not enough toilet paper and washing up liquid. The cleanliness could also be improved. For example, there was a used cup in the cupboard and no one has cleaned the windowsills for a longer time.
I think there is a kindergarten in one of the neighbouring houses, so it can be quite noisy in the courtyard aswell.
However, the price-performance ratio is completely fine, the check-in went smoothly and Ulvi always answered messages promptly. Thank you again for checking in earlier and checking out later, that was super kind. Recommended for a short couple holiday!
