This is the perfect location for a stay in Barcelona. The beds are super comfortable and the space is huge. Be aware that the walls are quite thin so we were woken up by a baby next door a few times in the night so bring ear plugs but it didn't bother us too much.
The area feels extremely safe and the locals are all friendly. Peter checked us in and was really helpful and kind and showed us how everything worked and answered all our questions.
There is a tourist fee, this is by the catalonian government and is paid to any host that is renting out an apartment for tourists. So be aware that there is a small additional fee when you arrive but you would get this in most places in the area.
All in all, we really enjoyed our stay here and would definitely come again.
