Writing on behalf of my guest as I wasn't able to come.
Flat is cosy, ideally for 1-2 people, but 3 is fine too. Basic amenities provided in the kitchen and some juice and milk left in the fridge which is very nice detail.
My guest raised concern over bed not being that comfortable however it may be individual.
Also as others stated at night time it got noisy from people residing above, and the light got through the glass panel.
Again as previously stated I too got an email day prior flight to bring own towels and sheets, which I find is a bit irregular.
The location is fantastic, bang on right in the city center close to any major sight within walking distance. For the price of it it's a good choice.
