Helena is a great host! She is very friendly and always ready to help you) she gave us many recommendations where to walk, to eat and to spent a nice time in the city.
Appartement is situated 1 minute from Cathedral de Barcelona, it is a grand 4 room flat with 3 rooms for guests and one for Helena and her little lovely daughter, big kithen and bathroom. We was in a biggest room for 3 persons. Helena provided us keys, so we could come home at any time we wanted (of course without making noise). Just 2 minutes from Helena's place is a bakery and 24h supermarket and of course there are plenty of restaurants because it is the center of Gothic Quarter.
So, I recommend Helena's appartement everybody who wants feel like at home in new city.
Have a good trip!))
