Orlando's place was enjoyable for our 5-day stay in Madrid. The place has a great balcony and the AC was much appreciated during the hot summer days. The apartment was also very quiet at night despite being on a busy street in the city. My only request would be to have more than 2 sets of towels in the apartment.
The location is great - Lavapies was central to most other neighborhoods and all things we did were within walking distance of the apartment. Orlando was a great host. He was very communicative and even let us store our bags early while the apartment was being cleaned prior to check-in.
