Pros:- pleasant, quiet apartment located near the Cuatro Caminos station;- the key-box check-in system is very convenient; - we were able to drop off our bags first thing in the morning, which made things much easier for us; - generally well-equipped, though we missed having a toaster (we used the frying pan to toast bread ).Cons: - it seemed like it hadn't been cleaned recently (overall it was clean, but there was some dust); - the sofa bed wasn't made up and we only had one sheet (we had to handle it ourselves, even though they knew the reservation was for 4 people); - there were only towels for two people (we had to ask for more; it turned out they were there, but inside a locked bag along with the missing sofa bed sheet and pillow cases); - communication was a bit difficult during the week (they took a while to respond on the day of arrival) and non-existent over the weekend; however, the person we spoke to was polite and managed to help resolve the situation. Overall, it wasn't a bad stay—despite the stressful moments that were eventually resolved—but there is room for improvement.
