We were in Barcelona for a whole week and absolutely loved our stay at Kitty's place. Given below are some points that you should take note of if you are considering to stay at Kitty's place :-
1. Proximity & access - It is a 20-25 min taxi ride from the airport. There are two bus stands both at a distance of just of two mins from the place. Thwre are plenty of important buses that stop at these stations that take you to/from centre of Barcelona. The tube/metro line station is 5-7 min walk from the place. However, in our personal experience, we didn't need any of this as the 20-25 min walk from the house to centre of Barcelona was just too enjoyable and we took the bus only when we had to travel further. For example Camp Nou
2. The Room - The room had a large bed which was very comfortable and well kept. It also had two large wardrobes. The best part of it is the stunning view of the harbour from the balcony.
3. Amenities - Kitty had made sure we had everything we needed. Towels, the bathroom, the bed all were very neatly kept and well maintained. Most importantly, Kitty was very helpful with anything we asked for.
4. Others
a. The beach is just a 5 mins walk and there are many restaurants, pubs and stores around which are open until late in the night. So over all it was pretty convenient
b. There is a e-bike shop on the ground floor of the same building. So if you are in the mood to just hire the bikes and not depend on public transport, this could be very convenient if you live at Kitty's place. This is because, if you take the bikes and return the bikes before 9pm, you don't have to pay the deposit of 150 euros. And as you are living just upstairs I found it kinda convenient to roam around the whole day, come back and deposit it on the ground floor and head up to Kitty's house.
In a nutshell, it was a great place to be during the time we were in Barcelona and we would recommend this to anyone who is considering it.
