Pros: location, check in, communication, and cleanliness were all great.
Cons: the space itself isn't great for much besides sleeping, and even for that it isn't great. If you're trying to read or work for an hour or two, there's no real comfortable place to sit, relax, and focus. The apartment is also noisy, and not just the main common room that faces the street. No, the two bedrooms in the back of the apartment are close to some sort of neighboring dance studio, flamenco bar, or the like. You can hear the stomping/moving/thudding of feet late into the night, even past midnight. It made sleeping difficult, which isn't something you want to deal with when you've been exploring for hours on end each day. Lastly, you can easily hear your upstairs neighbors walking around, and given all the apartments in the building seem to be rented only to tourists, you can bet that the sounds won't just be common living noises.
