Sandra was an outstanding host. Extremely responsive and helpful. The apartment itself is excellent and great value for money. The location is ideal if you're a tourist. Walking distance to all the tourist sites (we never used any public transport, although took a couple of taxis). Right near the Palace, which was great. Lots of food options nearby - the infamous San Miguel market is just round the corner. Nothing to complain about here - I would highly recommend. Only things to note: (1) the apartment has very low ceilings. This is not an issue if you're staying for 3-4 days like I was, but if you're staying longer it might be. (2) There was no wifi in the flat which isn't ideal. Other that that, this was a great apartment and I'm glad I stayed with Sandra.
