Really great location, super close to Sagrada Familia and lots of amenities. Host was very helpful and informative, and gave us lots of good local tips about where to eat and visit. The lodging team sent lots of information regarding check before arriving, and they provide somewhere to leave your luggage after check out which is great. Surprisingly large flat, was very clean and had everything that we needed (the TV was not working but we did not use it anyway as we were out visiting the city, so this was not really a problem). The heating worked excellently.
The only thing to bear in mind is that the flat is very close to a busy road and therefore was quite noisy. Ear plugs are provided to help with this, but we did not feel the need to use them.
Overall, great value for money given the location and a good base for a city break especially if you are doing lots of sightseeing. Would definitely recommend.
