We enjoyed our stay in Sintra and the Casa Miha apartment contributed immensely to this. Starting with the warm welcome from Antonio and Mihaela and continuing on to the clean, well furnished and comfortable apartment, everything was near perfect.
The apartment had all the facilities we needed for a relaxing stay and provided an excellent base to explore the palaces, castle, qunitas and nearby beaches. We found the Uber-like Bolt service (accessible via an app) a convenient and cheap way to transport four of us to these places. The electric tram to Praia das Macas was also well worth the trip for a fun and leisrely trip down to the lovely sandy beach. For food, the Dom Pipas restaurant just across the railway bridge served good local food, the cafe attached to the library just over the road was both cheap and provided great views across to the National palace and the Bar Salon Cintra across the road from the supermarket 10 minute's walk away was a good place for an evening drink. A huge glass of wine for just 2.50 euros was the best value we experienced.
If travelling to Pena Palace, we'd recommend pre-booking the tickets, catching a Bolt taxi for around 8 euros, walking to the Castle and then walking slowly back down to the centre of Sintra. Stopping off at the cafe/restaurant Casa das Minas provides some of the best views over Sintra's national palace with its eccentric conical chimneys and rewarding yourself with some of their excellent local dishes and cold Sangria served by the friendly staff makes the walk well worth it.
All in all our stay in Sintra at Casa Miha was wonderful. Highly recommended.
