We had a wonderful time at Lluis appartment.
After the first night we found out the bed was not in good condition, Lluis was very fast with first repairing and then replacing part of the bed. After this we slept very well.
The balcony was really nice and we used the pool quite a lot during our stay. The appartment is very well located, you can easily reach every part of the city by foot, subway or bus. The house is not large but has everything you need for a great stay in Barcelona. Would stay here again.
