Daniel's place is very nice, the location is great and by Metro all sights in the city are in 20 mins proximity. We found the place spotless clean and with basic necessities - like coffee, tea, water and morning snacks - equipped, also with fast internet, AC on both levels and 2 toilets + a shower with nice hot water (also towels and shower gels/shampoo).
Daniel was very responsive and was getting back to us with clear explanation on how we should enter and return the flat when we leave. The corner sounded a bit noisy first, but at the end it didn't disturb us and we could relax/sleep well on all of the days of our stay.
I can only recommend Daniel's place to stay if you are a group of 3-4 and want to have a great time in Barcelona.
