The flat is in a great, quiet neighborhood. There were a few small restaurants and markets around for us to be able to pick up the essentials or grab a coffee in the morning before we were on our way. The flat is very close to the Lesseps Metro stop on the L3 line which directly brought us to a number of places we wanted to see. It is also about a 20 minute walk (mainly uphill) to Parc Güell. The close proximity to the park allowed us to knock that out as soon as we got there so we could explore other areas on the rest of the trip.
Overall, the flat was very spacious and was spread across 3 floors (including the roof deck). The building had an elevator which was very convenient given we were on the top floor. My Space Capital also brought us a really lovely welcome gift that we enjoyed on the balcony. The only negative about the apartment was how uncomfortable the beds were. I ended up sleeping on the couch for the majority of the trip. We didn't use the pool during our stay so I can't comment on that but it was great to know we had that as an option.
