Easy check in procedure. We came into Barcelona around late evening but the host was super responsive and there when we arrived. Location is very ideal in that is a 7 minute walk from the city center and you are very close to all the main attractions. There are two good bakeries a block away and some good coffee as well. There is also plenty of space and a good fit for 5-6 people.
If you get a chance, I highly recommend taking the metro to the Vallcarca station and hiking to the top of Tibilabo, the mountain temple that oversees Barcelona. It was a half day trip for us and super fun and very achievable from this location. Skip the funicular and do the hike. Takes about an hour one up and 45 minutes down. You get an amazing perspective and feel totally disconnected.
