We had a great stay in Barcelona, however, we have divided feelings about the flat. With a few investments it could be a five star, but unfortunately, it is not right now.
On the bright side, the flat is ideally located, it is a beautiful old flat with a lot of space and the communication with the owner was really smooth. We needed a baby chair, and within an hour it was there.
What can be improved is pretty straightforward but really impacted our stay. The beds need to be changed, they are not comfortable and the beddings are of a poor quality. The furniture is generally worn down and does not reflect the beauty of the flat. The kitchen lacks a few basic amenities such as a teapot, a carafe, dishes that can go in the oven, tea towels, etc. which makes it hard to have a nice supper there, and the oven is very old. Finally, as it was January the flat got cold at night but the radiators were not on, we had to use the ACs which were extremely loud all night.
