Overall we had a nice trip. The location was extremely central.. Lots of public transportation options - and walking distance to all the sights. A couple of pointers:
1. The first three days it got pretty hot in the afternoon. it'll be good to have some sort of a fan in the rooms. It got pretty hot.. Especially as we wanted to come and take a siesta in the afternoons.
4. The place was quite cramped for a family of 4. Would have been ideal for 2 or 3 people. Especially with limited open space.
5. Finally, it would have been nice to have one extra pair of keys. A lot of coordination was needed with a family of 4 to get around with just one key - especially as the apartment complex also has a restricted access.

Overall we really enjoyed our trip - these things would have made it perfect.
The host was excellent. And very very prompt with responses.
