We stayed in Olalla's apartment as two adults and two kids (4 and 2 years old). Olalla had sent very detailed info about the apartment and area ahead of time, which was very helpful. We met Olalla's friend for check-in and this went very smoothly. Her place was sparkly clean and had everything we needed for a comfortable stay. The only drawback was that the apartment was located up several flights of stairs without an elevator, however this seems very typical and resulted in a quiet apartment with lots of natural light. The location was very convenient and we were able to take short bus or train rides anywhere we wanted to go, and multiple places to eat within walking distance. The children especially enjoyed staying here as there were plenty of toys to play with. I would highly recommend this apartment, especially if travelling with kids.
