We stayed at this apartment for 5 days. The place was clean and very well equiped in terms of amenities for a very comfortable stay. It was also beatufully decorated with warm shades of red making you feel really cosy!
We met Isa, who is a very friendly person. She made us feel very welcome and helped us with information about the city. Apart from amenities (microwave, stove, coffee maker, washing machine - no oven), the host also provided us with coffee and tea, and a fridge full of refreshments.
There wasn't much sunlight in the place, although that didn't bother us at all, since the beautiful city of Barcelona called us to spend the best part of every day outside. We essentialy used the apartment only for our night's sleep. The walls were not soundproof but, from what we've seen, this must be true for most of the buildings in the city, so wouldn't really find a quieter place there.
Tip: brush up your Spanish, for almost noone speaks English in Barcelona!
Overall our stay in this beautiful apartment was a great one and we'd definitely stay there again on our next visit to Barcelona! Muchas gracias, Isa y Juan!
